Profile

In my own words

mirrored word-for-word from the Upwork profile · read 1 August 2026

With over 14 years of specialized software delivery leadership across telecommunications, hospitality, and AI/ML projects, I bridge the gap between high-level business strategy and technical execution.

Today, I combine my deep background in Agile, Scrum, and program management with hands-on full-stack development to build custom AI applications, intelligent automations, and scraping tools that solve real business bottlenecks.

Why founders, startups, and product teams hire me:

  • Product-Minded Delivery: I don't just write code blindly. Drawing on 14 years of software leadership, I understand your business objectives, map out precise scopes, and build user-friendly AI tools that actually drive value.

  • Agile Speed & Quality: I work in tight, highly transparent Scrum iterations. You get regular, functional updates, ensuring a reliable product with zero rollbacks.

  • Cutting-Edge AI Capability: I design and build full-stack interfaces powered by advanced LLMs like Gemini 1.5 Flash to automate repetitive workflows.

Here is what we can build together:

  1. 1Custom AI Applications & Dashboards

    • Bespoke web utilities (PDF/text summarizers, custom GPT agents, data analytics engines).
    • API Integrations: Connecting Gemini/LLM APIs directly into your websites, databases, or third-party tools.
  2. 2Web Scraping & Automated Pipelines

    • Custom high-performance Python scraping scripts to extract leads, pricing, or product data.
    • “Competitor Intelligence Radars” that automatically monitor sitemaps/pages and deliver structured weekly reports.
  3. 3Workflow Automation

    • Automating manual business processes by connecting custom scripts with Google Sheets, Airtable, or Make/Zapier.

If you are looking for a reliable, highly professional developer who understands delivery, structure, and quality, send me a message and let's discuss your product!

Why Sennable exists

The premise

Most AI consultancies demo systems they've never had to live with. Sennable inverts that: every capability on this site earns its place by running in production for Sennable first — publishing on real schedules, billing with real formulas, failing loudly and getting fixed.

That's also why the numbers here are conservative. They're read from ledgers, git logs, and platform read-backs, and where a number isn't verified, the page says so instead of rounding up. If that discipline is what you want applied to your systems, get in touch.
